for example a' machine adaptable for slicing meat, bread, vegetables and the like, andhas forone object the provision of ama chine which shall be light and quick and easy to.

Operate. Anotherobject is theprovision of a machinein which the; work being sliced. tends to'recede from the cutting plane'of the knife, when released; Another object'speci fically, is the'provisionof such a machine with means for holding the work in such fashion and at such an angle that it will tend by gravity to recedefrom the knife,unless positively thrust there/against. Another objectis the provision of means for positlvely thrusting'the work, against gravity, toward the cutting plane. Other objects willappea'rfrom time to time in the course of the specification and claims:

In order-to gauge the slice 1 the'rwork is thrust against the gauge plate As this thrust continues until theslice is entirely severed, I employa guard plate to I receive thethrust of'that portion of the work which has passed the cuttingedge. It is desirable to withdraw the work'from contacts,

with gauge and guard plates; except during. the-actualslicing operation. I find'thejtype of carriage herein shown'highly eflicienhfor engagingmember or surface; which is set at from guard and gauge plates unless positively example by the provision ofan inclined'work a sufficient angle; to cause the work to recede' thrust thereagainst. This recession mayfat one extreme, with arelatively low narrow' carriage, take theform merely of a' tendency on the'part of the work to pull back from the gauge and guard plates, to prevent-press sure of the work thereagainst.
